Specification of Letters Patent.

Patented April 23, 1907.

Application filed August 16, 1906. Serial No. 330,823.

.To @ZZ whom, it may concern:

Be it known that I, JESSE THEODOR PYLE, a citizen of the United States,and a resident of Amarillo, in the county of Potter an... State ofTexas, have invented a new and Improved Pile Structure, of vwhich thefollowing is a full, clear, and exact description.

This invention relates to certain improvements in structure formed ofsheet piling driven into sand or soft earth and having the enclosedmaterial removed, whereby the pile may be filled with concrete to serveas a foundation for bridges, buildings and the like. The walls of thestructure are made up of a large number 'of sections which are driveninto the sand or soft earth one at a time and each succeeding one u onbeing driven becomes locked tothe one ast inserted It is particularlyold to employ separable secI tions of this kind in the construction ofpiers, and it is further old to form these Sections in a large circle orring and excavate the material from inside the said enclosure, but a ifnot inoperative, where it is desired to drive piling to a considerabledepth, as a single row 1s not sufficient to withstand theenormouspressure upon the outside after the enclosed material is removedand before the concrete is inserted. i

By the use of my improved sections, piles may be driven to any depthdesired and there is no liability of the piles caving in beforel theconcrete is packed in lace.

Reference is to be ad to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures,

fl ure 1 is a diagrammatical plan of brid e pile showing the arrangementof sections; Fig. 2 is a side elevation the; eof; Fig. 3 is a horizontalsection of one of theT-shaped sf'ctions employed; Fig. 4 is a horizontalsection of another form; Fig. 5 illustrates one form of the extensibleweb; Fig. 6 illustrates a second form of the extensible web, and alsothe means for holding the jet tube in the first section inserted; andFig. 7 is a side elevation of the form shown in Fig. 6.

The simplest form of section which I employ, comprises a tube 1 having aslot 2, ex-

tending along one side throughout its entire length, and having a web 3,extending from the tube along its entire length on the side opposite tothe slot. At the end of the web is a head 4, whose Snape in crosssection is substantially a sector of a circle, and adapted to fit theinside of the tube of the next adj acent section, while a flangeadjacent the head passes through the Slot of this section.

On the web 3 and adjacent the head 4 are two fianges 5 which may beintegral with the web or of separate pieces rigidly secured thereto,which anges extend in the arc of a circle and spaced from the surface ofthe head at a distance slightly greater than the thickness of the Wallof the adjacent tube. '.lliese flanges fit the outer wall of the tubeadjacent the slot therein and serve to prevent the web of one sectionfrom extending more than the desired distance into thc slot of the tubeon the next adj scent section. These sections are driven into the sandone atatime, and as i each one is driven a jet tube 6 is inserted intothe tube 1 of the section and the material within the Gube is eitherforced or pumpedv out of said tube. It will be noted that after the irsttube is inserted, the slot in the second'will be closed by the head 4 ofthe first while the second is being inserted and the material may beeasily removed from the tube cof said second and each succeedingsection, but at the time the first section is driven, it is necessary toprovide certain means for closing the slot to prevent sand from cominginto the tube as fast as it is removed by the jet tube 6.

In Figs. 6 and 7, I have shown a jet tube 6, having a plurality of bands7 surrounding the same, and each band attached to a short web 8, havingfianges 9 fitting the outer surface of the tube. AS the first section isdriven into the sand it carries the jet tube with its bands 7 andslot-closing means 8 and 9, so that the sand may be removed from thesection and other Sand prevented from entering the slot. After the firstsection is inserted, this particular means is no longer necessary inconnection with the other sections and a simple jet tube is freelyinserted Within the tube of the second and each succeeding section toremove the material therefrom. As soon as one section is driven and thematerial removed from the tube, the latter is filled with concrete tostrengthen and rigidly hold the IOS -same in place. These sections areusually driven in the arc of a circle and as the last section is aboutto be inserted it is often found that the distance between the sectionson the 5 opposite sides of the remaining gap is greater or less than thenormal wid-th of a section, and to accommodate for this, I providecertain sections having extensible webs, Whereby the distance betweenthe tube and the ro head of said section may be made greater or less toexactly fill the space between the ad- `acent sections. This may beaccomplished y making -a section of two separate parts and. securedtogether the overlapping pori 5 tions-of the web by rivets l-passingthrough slots inl the overlapping portions, as illustrated inv Fig. 5,or one portion of the section may have two adjacent web members betweenWhich a web member of the other porzo tion of the section is adapted toslide, the

three members being held together by rivetspassing through slots as inthe form above described.

The modiiication of the extensible web is z 5 clearly illustrated inFigs. and 7.

A single ring of these sections is entirely inadequate and evendangerous. -When it is desired4 to sink a pile to any considerable depthand to strengthen the pile, I preferably 3o drive sections to form twoconcentric rings 11 and 12,-as shown in Fig. 1, said rings being spaced.and Vheld rigid by radial partitions 13. Both of the rings, and also thepartitions are made-up of the unit sections above described, but inorder to secure the partitions 13 to the concentric rings 11 and 12, Iprovide a form of section shown in Fig. 3, in which the web 3 has abranch web 14 rigidly secured at an angle thereto, whereby the tube 15is drivensi- 4o .multaneously with the tube 1 and junction bet-Ween tworows of sections at an angle witheach other is thereby perfected.

In certain forms of piers it is sometimes desirable to have two rows ofsections intersecting each other, as shown at 16 in Fig. 1, and Iprovide the form of section shown in Fig. 4 to be usedI in cases of thiskind. This form of section has two branch webs 14 attached to the mainweb 3, and one of said 5o branchwebs 14 has a tube 15, as in Fig. 3,while-the other branch web carries a head 4, said head and tube being atsubstantially the same distance apart' as are the head and tube of thenormal unit section.

In driving the sections to form a pier of the sha e shown in Fig. 1, thematerial is excavatedJ from eachof the enclosed spaces 17 as soon as thewalls forming one of said spaces are completed and the space illed 6oWith'concrete. -The space within the-inner ring of sections is likewiseexcavated and filled with concrete, so that -the completed pier is-'asolid mass of concrete having the sections embedded therein, saidsection having been employed merely as a Colfer-dam to hold thesurrounding material in place while the concrete pier was being iilledout.

It is evident that the improved form of sections above described may beemployed for placing the concrete foundations in sand at any de th, andis particularly useful Iwhere quic sand is encountered. The sections maybe employed either for placing c oncrete piers, bridges, or foundationsof buildings, or for anyother similar purpose. For

cofer-dam work the sections are employed as in the building of concrete'piers but the spaces 17, enclosed by thesections, are not filled withconcrete, and the row of sections surrounds theplace where it is desiredto place any suitable structure on the river or ake bed, and when saidstructure is perfected, the sections may be removed without the samehaving been injured in any Way, and said sections may be again employedfoi' similar work.

^ Having thus described my invention, I

claim as new and desire to secure by Letters Patent:
